802.11n Facts Part Three
If you didn’t read facts #3 and #4 check them out first, but here’s 802.11n facts #5 and #6…
Although a new POE (Power-Over-Ethernet) standard, 802.3at is being worked on, the current POE standard, 802.3af may not supply enough power for access points with configurations of 3×3 or more antennas. Workaround may exist if users change the number of antennas or devices per PEO switch, but for now this lack of power supply is an important consideration.
Users may need to upgrade their access point’s wired network connection to Gigabit Ethernet because of high data throughput. According to Cisco, a 40-MHz channel in the 5-GHz band can place a peak demand on its Ethernet connection of as much as 300 to 400 Mbps. This will prove to be too much for a single or double 100 Mbps Ethernet connection to support.
